HydrauMesher is a Python QGIS plugin for generating unstructured meshes. It's based on seamsh.
HydrauMesher relies on Python3 and requires packages which are listed in requirements.txt (not in line with QGIS principe) and soon in metadata.txt. The pluggin works for QGIS3.3X, and we recommanded QGIS 3.38.2 for CNR usage. For internal usage, you can install HydrauMesher by launching the batch file. Once this has been done, simply check it in QGIS under Extensions --> Installed.
HydrauMesher includes a folder of test cases. These are examples from the simplest to the most complex. Some test cases are examples of functionality that doesn't work. The table below shows the test cases.
| Folder name | Work / Not working | Description |
|---|---|---|
| 00_Boundary_NOK | NW | Only a boundray |
| 01_Boundary_HL_NOK | NW | Boundary and a hard line |
| 02_Boundary_HL_DZ | W | Boundary, hard line and density zone |
| 03_BD_Hole_HL_DZ | W | Boundary with a hole in the polygon, hard line and density zone |
| 04_BD_Holefull_HL_DZ | W | Boundary with a hole in the polygon made by an other polygon, hard line and density zone |
| 05_BD_HF_HL_DZs | W | Boundary, hard line and density zones |
| 06_BD_HF_HLs_DZs | W | Boundary, hard lines and density zones |
| 07_BD_HF_HLs_refine_DZs | W | Boundary, hard lines refined (more points on a line) and density zones |
| 08_BD_HF_HLs_closest_DZs | W | Boundary, hard lines closest than the density zone and density zones |
| -1_Real_test_case_timer | W | Boundary, hard lines closest than the density zone and density zones. Real test case to compare HydraMesher to other software |
